I finally found a 12 volt photo control http://www.precisionmulticontrols.com/Photocontrols/Lo-Voltage.html

Lowes & Home Depot sell them made by Intermatic all day long in their low voltage lighting section.

I poured over the intermatic controllers and the circuit diagrams they have on their website. They seemed to be 120vor even higher voltage tho they may be controlling 12v ac landscape lighting systems. Even thought of using a 12dc to 120v ac converter just to run the controller but i figured it would use more enegry then it saved.

At Lowes in the LV section where all the green boxes are.

That is why on their cheap transformers they have three posts. $10
